STANCHION.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed May 21, 1914. Serial No. 840,078.

To all whom it may concern:

Be it known that we, ALEXANDER TUSGANY and LOUIS J. PETERSON, citizens of the United States, residing at St. Albans, in the county of Franklin, State of Vermont,

have invented a new and useful stanchion,

of which the following is a specification.

One object of'the present invention is'to provide a stanchion having a keeper adapted to be reversed, to the end that the stanchion may accommodate stock of different sizes.

Another object of the invention is to provide novel means whereby the stanchion is prevented from rotating;

It is within the scope of the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes'in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from thespirit of the invention.

In the accompanying drawing :Figure 1 shows a stanchion constructed in accordance with the present invention, Fig. 1 being a front elevation wherein divers parts are broken away and sectioned; Fig. 2 is a top plan of the stanchion frame proper; Fig. 3 is a vertical transverse section taken through the overhead support and the upper portion-of the stanchion frame; Fig! 1 is a fragmental longitudinal section "taken through the upper portion of the'stanchion frame; and Fig. 5 is an elevation showing in detail, the resilient means whereby the suspending chains of the stanchion are tightened up.

In the accompanying drawing there is shown a stanchion frame comprising a side bar 1, a head 2 and a foot 3, these parts being rigidly connected to form a part of the stanchion frame. In the upper face of the foot 3 near to one end thereof is formed a recess 4. 'In the head 2 is formed a slot or open ng 5. A. keeper 6 is shown and is pro.- vided along one edge with a projecting shoulder 7. The lower end of the keeper 6 is mounted to rock in the recess 4 and the upper end of the keeper 6 moves in the slot or opening 5 in the head 2. No pivot element is employed for connecting the keeper 6 to the foot 3, the lower end of the keeper being gravitationally held in the recess 4:.

The projecting shoulder 7 on the keeper 6 may be disposed away from the side bar 1 and then the stanchion is in a position to accommodate relatively large stock. If desired, the keeper 6 may be pulled up endwise out of the opening 5 in the head 2 and be reversed, so that the shoulder 7 lies adjacent the side bar 1, the keeper 6 being restored to the position indicated in Fig. 1, saving for the fact that the shoulder 7 now projects toward the side bar 1. By the operation above described, 7 the distance between the inner edge of the keeper 6 and the inner edge of the side bar 1 will have been reduced and the stanchion willbe in a position to retain calves and small stock.

In order to prevent the keeper 6 from being withdrawn when in a closed position, a pin 8 extends across the opening 5 of the head 2 and is adapted to engage the upper end of the keeper when the keeper is disposed in the dotted line position shown in Fig. 1. When the keeper6 is closed and in the dotted line position of Fig. 1, the keeper is held against lateral movement by means of a lock 9 of any desired construc tion. In Patent No. 1,084,17 9 there is shown, described and claimed, a lock which will be found convenient for use at the point indicated. A detailed description of the lock, therefore, need not be entered into inthis specification.

An angular latch 10 located in the opening'or slot'5 of the'head 2 and'is sup-' ported on a pivot element 11, the latch ineluding aprojecting finger 12. When the entering a recess 14 formed in an overhead support 15. The latch 10 exercises two functions. First, it constitutes a means whereby the stanchion frame is prevented from having a pivotal movement, and second, because the latch 10 bears on the upper end of the keeper 6 when the keeper 6 is in an open position, the keeper cannot be withdrawn endwise. It will now be obvious that the keeper 6 can be withdrawn and reversed, only when the keeper lies in a position intermediate the pin 8 and the latch 10.

Passing to the means whereby the stanchion is supported for. lateral swinging movement, or, stated differently, for rotation about a vertical axis, it will be observed that there is shown in the drawings a foundation 16 which may be a portion of the stall floor, there being an anchor plate 17 mounted on the foundation 16 and a chain or other flexible element 18 being connected with the anchor plate. By means of an eye-bolt 19 or the like, the upper end of the chain 18 is connected with the foot 3 of the stanchion. An eye-bolt 20 is mounted in the head 2 of the stanchion frame and is connected with the lower end of a chain 21 passing upwardly through a recess 22 formed in the overhead support 15, the upper end of the chain 21 being connected with an eye-bolt 23 passing through a bearing 24 secured to the upper face of the support 15. A compression spring 25 surrounds the shank of the eye-bolt 23 and abuts at its lower end against the bearing 24%. The eye-bolt 23 carries adjacent its upper end a washer 26 held in place by means of a nut 27, the washer 26 bearing on the upper end of the spring 25.

Obviously, the function of the spring 25 is to force the eye-bolt 23 upwardly, thereby tightening up the chains 18 and 21. An adjustment in the compressive effort of the spring 25 may be attained by rotating the nut 27 on the eye-bolt'23. The bearing 24L exercises a two-fold function. First, it serves to support the eye-bolt 23 for longitudinal sliding movement, and for rotation, and secondly, it serves as a thrust bearing for the spring 25.

In practical operation, the chains 18 and 21 are tightened up by the action of the spring 25 and an adjustment is obtained through the medium of the nut 27 'Ihe latch 10, engaging the overhead support 15, prevents the stanchion from swinging on a vertical axis when the keeper 6 is in an open position. The latch 10, further, prevents the keeper 6 from moving endwise when the keeper is in an open position. When the keeper 6 is in a closed position, the keeper cannot move endwise owing to the presence of the pin or projection 8 in the head 2. The keeper 6, when its upper end lies between the latch 10 and the pin 8 may be removed and be reversed, so as to present the shoulder 7 either toward or away from the side bar, for the purpose hereinbefore stated.

Having thus described the invention, what is claimed is 1. In a device of the class described, a stanchion frame comprising a side member; and a frame supported keeper cotiperating with the side member, the keeper being proe vided along one edge with a projecting ing its lower end loosely seated in the re-' cess, the keeper being adapted to engage the latch, to cause the latch to coact with the support when the keeper is in an open position, the latch engaging the keeper to hold the lower end of the keeper in the recess.

3. In a device of the class described, a stanchion frame including a foot and a head; an overhead support; means for supporting the frame 1 for lateral swinging movement; a latch pivoted to the head and adapted to coact with the support to hold the frame against lateral swinging movement; a keeper having its lower end loosely held upon the foot for rocking movement, the keeper being adapted to engage the latch to cause the latch to coact with the support when the keeper is in an open position, the latch engaging the keeper to hold the lower end of the keeper engaged with the foot.

4. In a device of the class described, a stanchion frame including a side member, and a head having an opening; a keeper pivotally supported on the frameand pro vided on one edge with a projecting shoulder, the upper end of the keeper being mounted to move in the opening; an overhead support; means for 1 supporting the frame for lateral swinging movement; a latch pivoted to the head and operating in the opening, the latch being engageable by the keeper to cause the latch to interlock with the support and to hold the frame against lateral swinging movement, the latch engaging the keeper when the keeper is in an open position, to hold the keeper against endwise movement; a projection on the head and extended into the opening, the projection coacting with the keeper to hold the keeper against endwise movement when as our own, we have hereto aflixed our sigthe keeper is in a closed positlon, the keeper natures in the presence of two witnesses.
